CASEMIJNT WINDOW.

Application filed August 28, 1924. Serial No. 734,772.

T o all whom t may concern.'

Be it known that I, ARGHIE E. VVALKEB,

a citizen of the United States, and a resident of Portland, county ofMultnomah, State of Oregon, have invented a new and useful Casement`Window, of which the Jfollowing is a specification.

This invention relates to easement windows, especially of theiii-swinging type of windows and has for its object an improved weatherstrip construction for preventing wind and rain from passing between thewindow sill and sash when the sash is closed, and also provides forlocking the window in closed position. i

In the drawings hereto, Figure 1 is an elevation of the lower part of aninswinging easement window positioned in its window frame, all as seenfrom the inside of the room, and with a portion of the sash kbroken awayto reveal the construction of the weather strip.

Figure 2 is an enlarged vertical section of the sash and sill as seenfrom the line 2 2 u of Figure 1.

Figure 3 is a front View of the link connection which lifts the stripwhen the knob is turned, and Figure 4 showsthe locked position of thelink with the strip raised.

In further detail, the drawing shows the usual window frame 1 with aeasement sash 2 therein and hinged at 3 to swing toward the observer andwhich in this case is supposed to be inward.

At the lower edge oit' the sash is a movable strip 4 which is raised orlowered by turning the knob 5, but which is resiliently urged downwardby spiral springs 6 seated in depressions 7 surrounding guide pins 8fixed in the sash but slidably projecting into the strip for guiding itsrising and falling movements.

In Figure 2 the relation of the strip 4 to the sill is clearly shown andit will be observed as having a stepped lower edge 4 to overhang therear stool or raised edge 9 of the sill 9.

The strip also has a tongue 10 along its upper edge sliding in a slot 11in the lower edge of the sash and is further guided by metal plates 12and 13 secured to the sash and projecting downwardly on opposite sidesof the strip 4 and which pia-tes, espe7 cially the forward one 13,prevent the entrance of moisture to the strip which might otherwise rundown the window and gain an entrance to the working parts.

In this connection it should be observed that the plate 13 is bent atright angles to pass under the forward edge of the sash and then againto pass upward inside of the slot' 11, and again bent to lie against theupper wall of the slot and to which it is secured, thus forming anabsolute barrier against the rains gaining admission through anycrevices. Y

At the center of the tongue 10 of the strip is a hoo-k 14 over which alink 15 is pivoted for raising the strip in the slot upon turning theknob 5.

The knob 5 has a shank 16 rotatably supported in a suitable socket 17secured to the sash, and at the inner end of the shank is a plate 18having two projecting pins 19 and 20, one of which (19) engages the linkto raise it with a crank-like motion upon turning the shank in thedirection indicated by the arrow in Figure 3 of the drawing, while theother pin (20) acts as a stop against a cut out portion 15 of the linkat a time when the link has beenvcarried just over center so that thestrip will lock in elevated position upon turning the knob as far as itwill go to permit free opening or closing of the window.

In contemplating Figure 2, it will be seen that with the strip loweredand interlocked with the stool as shown, the sash is also locked againstopening from the outside, thereby dispensing with any other lockingdevice, at least, at the lower end of the sash.

I claim:

In a window having a hinged sash, a movable weather sealing strip at theedge of the sash adapted to engage the frame of the window, and handcontrolled means on the sash adapted for withdrawing the strip from suchengagement comprising a revolubly supported knob having a shankprojecting into the sash above the groove and carrying twoipins at itsinner end, and a link pivotally connected to one pin and to the stripadapted to stop against the other pin when the strip is withdrawn.
